` 'PORTABLE HEATING APPARATUS,

1 Application lcd September 10, 1924. Serial No; 736,935.

In 4the manufacture of glass'products by. the well known cylinder drawing process great difficulty is encountered inthe production of a clear product'of uni-forml thickness owing to the inequality ofthe temperature of the moltenA glass before drawingl operation-due tol `various causes but vparticularly tothe cooling established tothe portion of the molten glassy contacting'with the side of the ladle while being conveyed from the furnace to the drawing pot.

The primary object of this' invention ris to provide a heating apparatus, in a'lmanner as hereinafter set forth, which will quickly reheat the molten` glass afterthe samer has been deposited in the drawing pot to establish a mass of uniform consistency and free from all bubbles and blisters;.under *such conditions insuring a superiordra'wn pr'oduct, uniform throughout, and free fromA all defects ordinarily encountered irl-the manufacture of glass by the drawingprocess;l

Further important objects of thisinv'ention are to provide a device of Vthe type stated, which may be readily shifted to and from the heating position; vwhich is simple in its construction and arrangement, strong, durable andA efiicient in its use; which includes novel means' for maintaining yits operating temperature g, which is positive in its action, compact, adjustable'and comparatively inexpensive4 to manufacture, install andV operate. i

l/Vith'the foregoing and other 4,objects in view, whichwill Aappear `asthe description proceeds, the invention residesr in the ,'.de- 'e tails of construction hereinafter described and claimed, it being understood *that lchanges Vin theprecisecenibod'iment of thein- Aventi'on herein? disclosedl can be -Inadef With- -in the 4scope ofvthec-lairns hereuntof appended without departing from the spirit f the in`ven'tion v 1 Y i Y In `-the drawing forming f a, portion of this specification g and wh'erein like numerals of referenceA f designate corresponding parts throughout the several views":-,-

Referring detail to the drawing 1 kdenotes a rigidly fired. standardto which one en d of ar` horizontally disposed supporting arm 2'is hingedlyconnected, as indicated at 3. The supporting arm 2 is held in horizon. talalignment Lby a supportingrod which is capablf of adjustment hyffa turn buckle It5 mounted thereon. Oneend ofthe rod. is attached, as-at 6, adjacent .to the. free e'ndfof the supporting arm 2,-V and .the othercen'd thereofl isnrotatably connected, as at 7, to the standard 1- at somepdistance above the supporting larno connection. j y

The Vfree'V endof the-supporting larm 2 y,carries al fixed. pairofvertically disposed j bearing braclietsS, in 'whichan adjusting bar 9 ispivotally connected, as indicated at l0, intermediate vof its ends. e

The -attachmentof the hood,A 11 with the yoke 14:

Vis such that the former will at all times maintainv its horizontal suspension bycgravity..'`heperipheraly edge,` of lthev hood 11 .is formedl with a 4`depending `annular .ange 1,5,.-the1diarneter yof. which ,is commensurate to the diameter of the glass` drawingpot 1.6 -in connection Hwith .vhichy my heating ratusisfadapted toibeused. o

YThe under .Siae of] hey 'hood 11 tifaiaiiy' of ^constitutes fthe combustion, chamber l5 Athe heating apparatus, and when inthe upper end of theadjusting screw 19 is pro-A appa- 2 to shiftv therewith.

vided with a hand wheel 21 to facilitate the adjustment screw 19 in the block 17. This adjustmentV determines the clearance 22 required to best meet conditions found in practice, between the lower edge of the annular flange and the top edge ofthe drawing 16 to permit and stimulate combustion during the heating operation.-

ifi blower 23 is carried at the rear end of the arm 2, and is supported in a suitable frame'structure Qd which is fixed to the arm The blower 23 is driven by a motor 25 also mounted in the frame structure 2d. suspended from the supporting arm 2' by a plurality of carriers 27. The inlet end of the conduit 26 is connected to and communicates with. the blower '23, and the curved outlet end 28 thereof is positioned directly over and in registration with the aperture 29 formed centrally in the hood 11. The fuel supply pipe 30 supported in any suitable manner, is provided with an outlet 81-posi tioned in the blower 23 adjacent to the inlet end ofthe conduit 26. The fuel supply pipe 30 is provided with a regulating valve 32 and a universal joint 33. The latter is provided to permit of the'shiftable movement of the associated parts attending the operation of the apparatus.

The adniixture of air, provided by the blower Q3, with the gas supplied through Vthe supply pipe 30, constitute the combustible elements, which enter chamber 15 through the apertures 29, for combustion. The combustion will be directed on the top of the molten glass 3d and quickly reheat the latter until the consistency thereof is uniform throughout` the entire mass thereby assuring a uniform drawn product free from all defects.

If the capacity of the drawing pot 16 is 'sufficient to allow al number of drawing operations therefrom. the heating apparatus is utilized to reheat the mass to the righteonsistency after each drawing operation thereby obviating the. necessity ,of conveying a separate mass of molten glass from the melting furnace to the drawing pot 16 after each drawing operation. n

For maintaining the hood 11 at a constant operating temperature for instantaneous use at all times, a heating furnace 35 of rany suitable design and construction is positioned adjacent to the drawing pot 16.r The furnace 85 has the same radial disposition as the pot 16 so that when thehood 11 is shifted on its mechanism fromv the drawing Apot 16, it may be positioned directly over the heatine; furnace 35 which will maintain the hood 11 at a constant operating temperature until ui" d for again reheating the molten mass msi ed in the drawing pot 16. it wiilQ-cf course. be obvious that the intensity of the combustion for the success- A large conduit 26 isv form, proportions and minor details of con vstruction may beV resorted to without departing from the principle of the invent-ion, or sacrificing any of the advantages oft-he invention, which come within the scope of the` claims hereunto appended.
